Batten seam joint

ABSTRACT

A batten seam joint providing a leakproof joint between adjacent roofing or sheathing member includes a longitudinally extending extrusion having spaced upstanding flanges inwardly from the edges thereof and a centrally disposed bifurcated fastener section. The adjacent longitudinal edges of the roofing or sheathing to be joined are positioned over the upstanding flanges and bent downwardly therebetween and a cap strip of the roofing or sheathing material is formed with longitudinally extending down turned flanges which are doubled and of a size to fit over the spaced upstanding flanges of the extrusion. A plurality of cut sections of a different extrusion are positioned at intervals in the cap strip and these cut sections include centrally disposed depending fastener members for engaging the bifurcated fastener so as to hold the cap strip securely in position and complete the batten seam joint.

BATTEN SEAR/I JOINT BACKGROUND OF THE INVENTION 1. Field of theinvention This invention relates to batten seam joints of the typenormally employed to provide leakproof upstanding seam joints betweenadjacent longitudinal edges of sections of roofing or sheathing materialsuch as sheet metal or the like.

2. Description of the Prior Art Prior structures of this type usuallyemploy wooden batten strips over which the upturned longitudinal edgesof the roofing or sheathing material to be joined are shaped andfastened. Alternate constructions include metal shapes substituted forthe wood batten strips and metal fasteners holding the longitudinalupturned edges of the roofing or sheathing material in positionthereover (See U. S. Pat. No. 2,907,287 This invention eliminatesexposed fasteners and the openings through which the same have beenpositioned as customary in the prior art structures.

SUMMARY OF THE INVENTION A batten seam joint structure comprising anelongated member having spaced upstanding flanges longitudinally thereofand having a longitudinally extending bifurcated fastener membertherebetween, the inner opposed surfaces of the bifurcated member havinglongitudinally extending grooves therein, a plurality of clips each ofwhich has downwardly extending flanges on its longitudinal edges and acentral down turned portion having longitudinally extending ribs on itsouter lower surfaces, said clips being positioned at spaced intervals inan inverted channel shaped closure member formed of flexiblesheet-roofing material, the flanges of which are reversely bent onthemselves and arranged to cover and enclose the clips and theupstanding spaced flanges of the elongated member so as to hold thechannel-shaped closure member in position thereon and in clampingrelation to the spaced longitudinal edges of a pair of roofing sheetshaving their opposite edges shaped to provide hook like engagement withthe upstanding flanges of said elongated member.

DESCRIPTION OF THE DRAWINGS FIG. 1 is a fragmentary top plan perspectiveview of a roof structure incorporating the batten seam joint.

FIG. 2 is an enlarged cross-sectional illustration taken on lines 2-2 ofFIGURE 1.

FIG. 3 is a composite view showing in side elevation two portions of thebatten seam joint structure showing the ability of the same to be curvedin an outwardly or inwardly bowed shape.

DESCRIPTION OF THE PREFERRED EMBODIMENT In its simplest form the battenseam joint structure of this invention is comprised of an elongatedmember having a pair of upstanding spaced flanges 11 thereon, spacedinwardly from the longitudinal edges thereof and so as to define a pairof out turned flanges 12. The out turned flanges 12 are apertured atlongitudinally spaced intervals for the reception of fasteners such asscrews 13 by which the member 10 may be mounted to the roofing deck orsimilar structure.

By referring to FIG. 1 of the drawings in particular it will be seenthat a roofing deck structure has been disclosed and is in dicated bythe numeral 14 and that a section of roofing material 15 is shownsuperimposed thereon. The member 10 is positioned over the material 15and secured to the deck 14 by fasteners 13 and it will be observed thatadjacent sections of sheet-roofing material 16 are arranged so thattheir longitudinal edges may be positioned upwardly and over and downturned with respect to the spaced flanges ll of the member 10. In theenlarged detail of FIG. 2 of the drawings the roofing material 16 isshown with the longitudinal edges thereof so formed.

Still referring to FIGS. 1 and 2 of the drawings it will be seen thatmidway between the upstanding flanges 11 there is a bifurcated flange17, the inner opposite surfaces of which are sharply grooved as at 18.The bifurcated flange 17 forms a continuously extending fastenerconfiguration for the reception of a plurality of spaced clips 19 whichare seen in FIG. 1 of the drawings and one of which is shown in crosssection in FIG. 2 of the drawings. Each of the clips 19 has a pair ofdown turned flanges 20 defining its longitudinal edges and a centrallydisposed depending portion 21, the lower end of which is formed withsharpened ribs 22 on its opposite sides and thereby arranged for lockingengagement with the bifurcated flange 17.

The clips 19 are normally positioned in spaced relation within ininverted channel-shaped flexible closure member 23 formed of roofingmaterial which is preferably the same material as the roofing material16, the ends of which are being joined and sealed by the batten seamjoint structure.

In FIG. 2 of the drawings, the enlarged detail illustrates the downturned and upturned configuration of the flanges formed in thechannel-shaped flexible closure member 23 which covers the exteriorsurfaces of the clips 19 and the inner opposed surfaces of the flanges20 thereof. When the clips 19 are positioned in the channel-shapedclosure member 23 the same may then be applied to the member 10 inoverlapping relation to the flanges 11 thereof and the depending portion21 will then engage the elongated bifurcated flange l7 and the fasteningconfigurations 18 and 22 thereof will lock the assembly in position.

It will be seen that the upstanding flanges 11 are bent outwardly awayfrom one another in slight degree so that when the clips 19 and thechannel-shaped closure member 23 are applied longitudinal there issufficient resilience in the flanges 11 to insure a close contact withthe clips 19 as best illustrated in FIG. 2 of the drawings.

It will occur to those skilled in the art that the resulting batten seamjoint completely conceals the fastening means and at the same timeinsures a tight yet flexible seal between the longitudinal edges of thesheets of roofing material 16.

It will further be observed that the construction disclosed can beshaped easily to conform to outwardly bowed roofing sections or inwardlybowed roofing sections as seen in the two figures of FIG. 3 of thedrawings. In arranging the device to be used with roofing or mansardroofing sections wherein the ornamental appearance of a batten seam roofis highly desirable, the flanges 11 may be notched as shown in FIG. 3 ofthe drawings to enable the member 10 to conform to the particular shapeof the basic roof structure. It has been determined that in large areasof relative small curvature, the distortion capable in an aluminumextrusion from which the member 10 and the clips 19 are preferablyformed, it is sufficient to permit the construction to be conformed tothe small curvature without the notching of the flanges 11 as seen inFIG. 3 of the drawing. Although but one embodiment of the presentinvention has been illustrated and described, it will be apparent tothose skilled in the art that various changes and modifications may bemade therein without departing from the spirit of the invention.
